возможно ли самостоятельно нарисовать инструмент с нестандартным зубом в Pro/Engineer 3.0?

ответ положительный

Как? Если не секрет?

To Add a Sketched Tool
You can use sketched tools for Trajectory Milling or Trajectory Turning NC
sequences.
Using Additional Modules

1. On the Tool Setup dialog box menu bar, click Edit > Sketch.
2. The system increments the pocket Number by 1 with respect to the last one
currently in the Tool Table and generates a default Name for the tool. The
Offset field is left blank.
3. Modify Name as desired.
4. Click Sketcher.
5. The system starts the Sketcher user interface and opens a new window. Sketch
the tool section.

такой инструмент, форма которого задана в скетчере можно использовать только для фрезерования по векторам

Sketching the Tools for Trajectory Milling
For 2- and 3-Axis Trajectory milling, you can either use standard tools, or sketch
your own tool for the NC sequence. The tool is sketched as a revolved protrusion:
• The sketch represents half of the tool cross-section. The whole sketch must lie on
one side of the axis of symmetry. The axis of symmetry must be vertical, with
the sketch lying on the right.
• The section must be closed.
For a sketched tool, you can specify a control point other than its tip by adding a
coordinate system to the tool section sketch, as shown in the following illustration.
The tool will then be swept so that its control point follows the specified trajectory.
For standard (edited) tools, and for sketched tools with no control point specified,
the tip of the tool will be used. The tip of a standard tool is determined by the tool’s
control point. The tip of a sketched tool is determined as the lowest point of the tool
section sketch (the lower-left if there are several equally low vertices).
Note: Make sure to specify the tool offset option correctly when using a control
point. For example, if you select side edges of the slot and place your control
point on the periphery of the tool, choose None for the tool offset direction. Also
make sure to select the cut direction depending on the orientation of the
coordinate system used as the tool control point: when the tool travels along the
trajectory, the X-axis must point towards the trajectory while the Y-axis is
pointing up.
The following illustration shows specifying a control point for a sketched tool.

1. Select these edges
2. Sketch this tool
3. Tool control point
Note: Additionally, when defining a sketched tool for 2-Axis Trajectory milling,
you can place the coordinate system on the tool axis. The system then calculates
the tool diameter at the level where the coordinate system is placed, and uses
this diameter for tool offset. This provides you an ability to use the same
sketched tool for cutting in both directions. You still have to specify None as the
tool offset option, but you do not have to select the cut direction depending on
the orientation of the coordinate system.

Это всё хорошо. А как на счет обработки формообразующих поверхностей?

[Хочувсезнать]

никак, только стандартными инструментами - концевая, конусная, сферическая
